目的探讨采用显微手术治疗前床突脑膜瘤的方法和疗效。方法对1999至2006年收治的26例前床突脑膜瘤进行回顾性分析。其中,男8例,女18例,年龄为21～66岁,平均47.6岁。本组患者采用翼点入路或扩大翼点入路,术中辅以微血管多普勒技术指导肿瘤包裹血管的分离。结果26例患者中,SimpsonⅣ级切除6例,SimpsonⅢ级切除4例,SimpsonⅡ级切除16例,无死亡病例。结论利用显微手术可明显提高肿瘤全切除率,减少术后并发症,降低死亡率;对于明显侵犯海绵窦和颈内动脉等重要结构的残余肿瘤,可考虑术后放射治疗。
Objective To investigate the method and effect of microsurgical treatment of anterior segment meningioma. Methods A retrospective analysis of 26 cases of anterior segment meningioma admitted from 1999 to 2006 was performed. Among them, 8 males and 18 females, aged 21 to 66 years old, with an average of 47.6 years old. This group of patients using pterional approach or expansion of pterional approach, assisted by microvascular Doppler technique guided by the separation of tumor-wrapped blood vessels. Results Among the 26 patients, 6 were Simpson Ⅳ resection, 4 were Simpson Ⅲ resection, and 16 were Simpson Ⅱ resection without any death. Conclusion Microsurgery can significantly improve the total resection rate of tumor, reduce the postoperative complications and reduce the mortality rate. Consider postoperative radiotherapy for the residual tumor which obviously infiltrates the important structures such as cavernous sinus and internal carotid artery.
